The following program should fail to link, since <anonymous>::B::x is declared
but not defined. However, the program compiles, links, and runs with gcc 4.2.1
and with a relatively recent 4.3 snapshot.
This same program fails to build under gcc 4.1 and earlier, icc 8.1, and Comeau
test drive.
struct A {
A(void *) {}
};
namespace {
struct B : public A {
B() : A(&x) {}
static int x; // declared, but never defined
};
}
int main() {
B::x = 0;
}
